摘要： There are provided a method for producing a magnesium alloy sheet having good press formability and a magnesium alloy coil stock obtained by coiling the magnesium alloy sheet. After a raw material sheet 1 composed of a magnesium alloy is preheated to 280° C. or less, the heated raw material sheet 1 is rolled with a reduction roll 3 and the obtained long rolled sheet is coiled. The surface temperature of the reduction roll 3 is set to be 230° C. or more and 290° C. or less. The preheating, rolling, and coiling are repeatedly performed in a continuous manner. By setting both the temperatures of the raw material sheet 1 and reduction roll 3 to be certain temperatures, the rolling property of the raw material sheet can be improved and the raw material sheet can be properly rolled in a continuous manner. In addition, a variation in temperature in the width direction of the reduction roll can be suppressed and uniform rolling can be performed, resulting in the production of a long magnesium alloy sheet. In this magnesium alloy sheet, working strain is sufficiently introduced by rolling and an increase in the size of crystal grains is suppressed. Thus, the magnesium alloy sheet has good press formability. Furthermore, a coil stock in which telescoping is not easily caused and that has good appearance is obtained.

摘要： Provided are a rolled Mg alloy material which has a wide width and whose mechanical properties are uniform in a width direction, a Mg alloy structural member produced by plastically working the rolled Mg alloy material, and a method for producing the rolled Mg alloy material. The method for producing a rolled Mg alloy material includes rolling a Mg alloy material with a reduction roll. The Mg alloy material has a width of 1,000 mm or more, and the reduction roll has three or more regions in the width direction. The temperature is controlled in each of the regions so that a difference between a maximum temperature and a minimum temperature is 10° C. or less in the width direction of a surface of the reduction roll. The variation in the rolled state in the width direction can be reduced by reducing a difference in temperature over the width direction of the reduction roll. As a result, it is possible to produce a rolled Mg alloy material whose mechanical properties are substantially uniform in the width direction.

摘要： A martensitic stainless steel pipe, which comprises specified quantities of C, Si, Mn, P, S, Cr, Ni, Al, N, Cu, Ti, V, Mo, Nb, B and Ca, and the balance being Fe and impurities, has satisfactory toughness at a high strength of 650 MPa or more by yield strength and also excellent hot workability. Therefore, it can be used as a high-strength martensitic stainless steel pipe for carbon dioxide gas corrosion resistant use, to be used in oil and/or gas well environments containing no hydrogen sulfide but carbon dioxide gas. This high-strength martensitic stainless steel pipe is an inexpensive martensitic stainless steel pipe, which does not require an addition of large quantities of expensive elements such as Ni and Mo, and moreover does not require the control of the content of P to a value less than 0.010% by mass.
